This look rational. Note that even with the grid surviving, we would not need the usual transcontinental grid, but a small clustered nano/microgrid.
One place for optimisation is connection different consumers like housing and industry, or commerces, and offices, electric cars, ... I'm not convinced Powerwall will be less expensive than LENR capacity, but why not. Just pluging to the block-microgrid, or just to your building nano-grid may be more efficient than powerwall... or you share the powerwall. some UberPop sharing economy may replace utilities. whatever happen they have to change their model. like for Telcos they cannot sell energy, except to industrialists by MW... they will sell maintenance, renting, capacity, sharing of clients capacity. The economic model of big corp will probably mostly die as it was required for 19th industry, for mass production of clone products in big zombie-workers factories, for continental grids and GW powerplants. modern economic model is fabless design, independent distributed production by specialized SMB working in ecosystems, distributed sales through platforms using grid computing in cloud, proposed by uberPop style of micro business selling computer nodes power. 2015-12-16 16:21 GMT+01:00 Jed Rothwell <[email protected]>: > Here is a situation that I think would be unfair to the power companies, > and unsustainable.
